A Phoenix man was arrested Tuesday on suspicion of assaulting a woman last year after he knocked on the woman’s apartment door and shouted that he needed help, according to court records.

Police arrested Brent Lee Barrett, 51, at his residence near Seventh and Garfield streets and booked him on suspicion of sexual assault, kidnapping and sexual abuse, according to court documents.

The victim, a 28-year-old woman with autism, told police she was awoken one night last year in mid-March by someone knocking on the door of her apartment in a complex near Portland and Second streets, according to court records. A man yelled through the door that he needed help, but when she opened it, he entered and pulled her to the couch where he sexually assaulted her, according to police reports.

The woman recognized the man and described him as a transient whom she had given food to the month before, according to police. Barrett has been living at his current residence for 10 months, according to the documents.

The victim told police that after the assault, Barrett told her to not “snitch” on him, according to the documents.

Barrett was held without bail because of the nature of the allegations, according to court documents.
